Many electric vehicle owners often choose when they need to replace the battery of an electric vehicle. After buying the battery back, they will go home to assemble and replace it by themselves. However, if the electric vehicle battery is not installed correctly, not only the quality of the battery will be affected, but the battery also has potential safety hazards. Here I will introduce how to assemble the electric vehicle battery: 1. Check the process of disassembling the battery It is necessary to check the quality of all connections. At the same time, check whether the fuse holder, charging socket, and the electric vehicle battery lead wire are in normal and reliable contact, and fasten all connections. Those that need to be replaced should be replaced, and their reliability should be focused on, and those that are unreliable should be replaced. 2, installation must install the electric vehicle battery in accordance with the instructions in the battery box. In fact, most of the batteries in the battery box are connected in series. Use a copper wire of no less than one square to connect each battery in series with a soldering iron. Finally, there are two output terminals, positive and negative. , Welded on the two segments of the output socket, be careful not to connect them backwards, and must correspond to the positive and negative poles on the charger. Otherwise, the result will be serious. 3, try it out After installation, use a multimeter to measure the voltage of the battery output port. The actual battery voltage is 2~5V higher than the standard voltage, and it can be put into normal operation after it is normal. Through the above three steps, you can basically learn how to assemble electric vehicle batteries. Of course, it is recommended that you go to a professional electric vehicle battery assembly shop to assemble the batteries. If it is incorrect battery assembly, the battery life will be shortened in the case of long-term impact and wear. Therefore, it is very important to learn how to assemble electric vehicle batteries.
